Why Choose the ABB 1SDA058921R1 Emax E6H/E/f/MS 4000 Switch-Disconnector?
The ABB 1SDA058921R1 is a SACE Emax E6H/E/f/MS 4000 four-pole fixed switch-disconnector designed for high-current DC switching and electrical isolation. Identified by ABB as E6H/E/f/MS40004pFHR1000VDCnew, this specialist configuration combines a 4000 A current rating with 1000 V DC operation, a full-size neutral and rear horizontal terminals.
The E6H/E/f/MS configuration is intended for switching and disconnection duties in demanding DC power systems rather than automatic overcurrent protection. Its four-pole full-size neutral arrangement provides four full-current poles, while the fixed construction is designed for permanent integration into compatible SACE Emax switchboards and distribution assemblies.
Rated at 4000 A and 1000 V DC, the 1SDA058921R1 provides substantial electrical capability for high-power DC installations. It also offers a 65 kA short-time withstand current for 1 s, a 1000 V insulation rating and a 12 kV impulse withstand voltage for robust performance in demanding distribution environments.

High-Current 1000 V DC Switching and Isolation
ABB SACE Emax /MS switch-disconnectors provide controlled switching and electrical isolation for high-current distribution systems. The E6H/E/f/MS configuration is specifically designed for demanding DC applications, allowing switching and disconnection duties to be separated from the overcurrent protection functions provided elsewhere within a coordinated electrical installation.
The 1SDA058921R1 combines a substantial 4000 A current rating with 1000 V DC operation and a 65 kA for 1 s short-time withstand rating. Its fixed four-pole construction, full-size neutral and rear horizontal terminals make it particularly suitable for permanent installation in high-capacity DC switchboards.
Typical Applications
- High-current DC power distribution systems.
- Industrial 1000 V DC switchboards.
- Main DC switching and electrical isolation.
- Fixed high-capacity switchgear assemblies.
- High-current DC feeder isolation.
- Industrial process and manufacturing power systems.
- Infrastructure DC distribution installations.
- Applications requiring four-pole switching with a full-size neutral.
